DIAC Memory Cell. Each memory cell contains a DIAC D1 and a capacitor C1. For this example, DIAC D1 is rated for 25V. Thus, it will turn on when the greater than 25V is applied across its terminals. The pulse generator Vp will be used to illustrated the operation of the memory cell.

Diacs are available at Mouser Electronics from industry leading manufacturers. Mouser is an authorized distributor for many diac manufacturers including Diotec Semi, STMicroelectronics & more. Please view our large selection of diacs below.

A DIAC, short for "Diode for Alternating Current," acts as a semiconductor switch that can operate in both directions. Meaning it can be triggered in both forward & reverse polarities. This bi-directional switching capability makes the DIAC essential in controlling AC power in various electronic devices.

The example's DIAC was rated for 25V, and therefore +VBO equals +25V. The figure exaggerates the current flow at this point. Some DIACs may have a small positive resistance region at the +VBO voltage, where current can increase while the …

diac符號類似於在相反方向上連接的兩個二極管。它在視覺上表示其在雙向進行電流的能力。此符號在交流電路中很重要。與標準二極管不同，diac使用標記為a1和a2或mt1＆mt2的非偏振端子，表明電流傳導可以根據施加的電壓從任一端子開始。
